We study an assignment type resource-constrained project scheduling problem with resources being multi-skilled personnel to minimize the total staffing costs. We develop a hybrid Benders decomposition (HBD) algorithm that combines the complimentary strengths of both mixed-integer linear programming (MILP) and constraint programming (CP) to solve this(More)
Benefit-cost analysis is required by law and regulation throughout the federal government. Robert Dorfman (1996) declares " Three prominent shortcomings of benefit-cost analysis as currently practiced are (1) it does not identify the population segments that the proposed measure benefits or harms (2) it attempts to reduce all comparisons to a single(More)
The Military Applications Society (MAS) is a democratically constituted professional society of open membership dedicated to the free and open pursuit of the science, engineering and art of military operations. It is the first society of the Institute for Operations Research and the Management Sciences (INFORMS). MAS advances research in military(More)
We study a project scheduling problem with multipurpose resources (PSMPR). A multipurpose resource is a resource unit that is " versatile " enough to perform different types of operations. A mixed-integer linear programming (MILP) and a constraint programming (CP) formulation for the standard PSMPR model are each presented in this paper. We also propose a(More)
